I’ve found this review of Jami: Peer to Peer Apps
“On the Mac, pictures are no longer saved directly in your Documents folder as they were in previous versions, they are somewhat more hidden in your user Library but still not encrypted. Any files sent to you are saved in /Users/[your account]/Library/Containers/com.savoirfairelinux.ring.macos/Data/Documents/. If you delete your Jami account the files are not deleted. If you then add a new account, any files sent to the new account are also saved in this same directory. So you now have files sent to multiple Jami accounts saved in the same directory together, with no encryption or other controls to prevent access.”
“While the Android client does not appear to leak files (none that I could find) the Mac version saves files sent to you in your user Library. This makes this app insecure for anyone using the Mac version or sending to someone else who is.”
Has the security issue with macos been fixed by now? I find it really sad that such a great and promising peer to peer cross platform software is not being recommended by messenger comparisons because of this flaw.
